upgrade from 12.10 to 13.x - says "no new release found"

I'd like to upgrade from 12.10 to 13.10, even if that means upgrading to 13.04 first

dell@dell:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.10
Release:    12.10
Codename:   quantal
dell@dell:~$ sudo do-release-upgrade
[sudo] password for dell:
Checking for a new Ubuntu release
No new release found
dell@dell:~$

I followed instructions from http://linuxg.net/yet-another-way-to-upgrade-update-from-ubuntu-12-10-to-ubuntu-13-04/, and upgrade ubuntu 12.04 to 13, and http://linuxg.net/update-from-ubuntu-12-10-to-ubuntu-13-04-by-terminal/, and Why is "no new release" found after I'm told its available?, and similar googles. they all tell pretty much the same thing, which I have tried. Software updater continues to say "The software on this computer is up to date". I have never been notified that 13.x is available.

Use the terminal to insert the following commands:

Upgrading to the new version:

sudo apt-get install update-manager-core
sudo do-release-upgrade -d

(-d will let you see new versions)

After the upgrade:

sudo apt-get update
sudo apt-get -f dist-upgrade`

Hope it helped you out.
